59-year-old-male underwent biopsy, after founding epigastric mass, and was diagnosed with B-cell lymphoma. He was treated as an aggressive lymphoma with R-CHOP. Because of neurtopenia, the planned 6 cycle regimen was not completed and a radiation course was administered. Since then the patient feels well, but continues to have prolonged and persistent neutropenia with mild thrombocytopenia. The expert suggests differential diagnosis of the bone marrow problem, and recommends additional diagnostic workup.

57-year-old male who was found to have back pain and hyperglobulinemia approximately. Marrow biopsy was consistent with IgG myeloma. He was treated with steroids and local radiotherapy with improvement in symptoms and a modest reduction in the M-component. He received melphalan-based autologous stem cell transplantation, which was complicated by reversible respiratory failure. Unfortunately, he relapsed and was treated with bortezomib and steroids for 6 cycles followed by thalidomide. The disease has responded to therapy.
